The Actiwatch is increasingly being used to investigate sleep. The aim of this study was to investigate which sensitivity setting of the Actiwatch is most suitable to detect sleep disturbance in older adults with intellectual disability (ID).
Two Actiwatch types were compared to polysomnography (PSG) in 10 older adults with mild ID, using a 1-min epoch-to-epoch comparison. Outcome measures were sleep detection percentage, wake detection percentage, and overall accuracy of both Actiwatches, and several sleep parameters.
The high sensitivity setting of the Actiwatch appeared most suitable to detect sleep disturbance in older adults with ID (wake detection percentage = 54.6%, sleep detection percentage = 89.7%). Sleep parameters calculated using the high sensitivity setting corresponded well to PSG outcomes. Outcomes were similar for both Actiwatches.
We recommend using the high sensitivity setting of the Actiwatch for clinical evaluation of sleep, and for epidemiological research in older adults with ID.
活动监测仪越来越多地用于睡眠研究。本研究的目的是调查活动监测仪的哪种灵敏度设置最适合检测患有智力障碍（ID）的老年人的睡眠障碍。
对10名轻度ID的老年人，将两种类型的活动监测仪与多导睡眠图（PSG）进行比较，采用逐分钟的逐时段比较。结果指标为两种活动监测仪的睡眠检测百分比、觉醒检测百分比和总体准确率，以及几个睡眠参数。
活动监测仪的高灵敏度设置似乎最适合检测患有ID的老年人的睡眠障碍（觉醒检测百分比 = 54.6%，睡眠检测百分比 = 89.7%）。使用高灵敏度设置计算的睡眠参数与PSG结果相当吻合。两种活动监测仪的结果相似。
我们建议使用活动监测仪的高灵敏度设置进行睡眠的临床评估，以及用于患有ID的老年人的流行病学研究。
